Construct is an HTML5-based 2D game editor, developed by Scirra Ltd.[3][4] It is aimed primarily at non-programmers,[5] allowing quick creation of games in a drag-and-drop fashion using a visual editor and a behavior-based logic system.

The primary method of programming games and applications in Construct is through 'event sheets', which are similar to source files used in programming languages. Each event sheet has a list of events, which contain conditional statements or triggers. Once these are met, actions or functions can be carried out.[6] Event logic such as OR and AND, as well as sub-events (representing scope) allow for sophisticated systems to be programmed without learning a comparatively more difficult programming language.[7] Groups can be used to enable and disable multiple events at once, and to organize events.[8]

Unlike many traditional development environments, Construct eschews selecting specific instances of objects when adding events, in favor of filtering through all instances of an object type on screen. When adding events, the editor allows the user to specify conditions or checks that must be fulfilled by each object instance on the screen before the event will be added or run by it. Events can be chained together using sub-events, allowing for more complicated behaviors to be created.[9]

Construct has the ability to export to several platforms that provide offline and native application behavior: Windows, OS X and both 32-bit and 64-bit Linux are supported by exporting to Node-Webkit. Doing this will allow the user to incorporate several features that HTML5 apps do not normally support, such as fileIO.[10] On October 23, 2012, Scirra announced full support for exporting to Windows 8Metro apps, including the incorporation of in-app purchases, 'snap' view states, roaming data, sharing, live tiles, touch input and accelerometer and inclinometer input.[12]

Construct 2 handles native mobile support for iOS and Android by utilizing third-party wrappers such as PhoneGap, CocoonJS, Crosswalk and Ejecta.[13][14][15][16]

Originally developed by a group of students,[18]Construct Classic is the free and open sourceDirectX predecessor to Construct 2, first released on October 27, 2007.[19] The most recent release is r2, released on February 5, 2012.[20]

On April 20, 2013, Construct Classic was retired to allow the development team to focus more on Construct 2.[21] Construct 2 added a JavaScript framework for programmers to use alongside the drag-and-drop editor.[3]

On October 18, 2012, Construct 2 was submitted to Steam Greenlight.[22] Construct 2 was in the first batch of software titles to be greenlit[23] on November 30, 2012. On January 26, 2013, Construct 2 was the second 'Greenlit' software title to be launched on Steam.[24]

On January 27, 2015, Construct 3 was announced in an entry in the official Scirra blog. New features include Mac and Linux support, multi-language support and third-party extensibility of the editor.[25]
